Strixonomy VS Code extension

Open VSX VS Code Marketplace

Strixonomy is the VS Code ontology IDE powered by Strixonomy. It provides the explorer sidebar, Entity Inspector, Query Workbench, Manchester editor, graph panels, reasoner views, and inline diagnostics.

The extension talks to the bundled Strixonomy LSP (strixonomy-lsp) — you do not need Rust installed for normal use.

Looking for the CLI or Rust library? See Strixonomy overview and Rust & CLI guide.

Quick start

  1. Install Strixonomy from the Marketplace or Open VSX (Cursor).
  2. Open a folder with .ttl, .obo, .owl, or other ontology files. Bundled language server works in Restricted Mode — Trust only if you set custom strixonomy.lspPath or strixonomy.robotPath.
  3. Open the Strixonomy activity bar → Classes → click an entity.
